The goal of this case study is to document an activity of the STEP UP research programme consortium which resulted in successful evidence utilization. This is to both demonstrate the positive impact STEP UP is having on family planning and reproductive health policies, as well as to document the process by which this was achieved so as to inform future research of successful strategies and lessons learned. By applying robust evidence, securing the support of decision makers, and engaging stakeholders, STEP UP enabled national and local decision makers to better understand the consequences of unintended pregnancy for adolescent girls’ schooling in Homa Bay County, Kenya. Through this and subsequent research uptake, STEP UP has successfully contributed to several impacts that include: -A reversal of attitudes of school principals, students, decision makers, and community members away from traditional negative perceptions of teenage pregnancy and towards one of understanding and support. -An increase in the proportion of out-of-school girls re-entering school. -Multiple local innovations to support re-entry. -Generation of evidence that provided a basis for the drafting of a new parliamentary bill to support girls’ re-entry into school.
